I just bought a 36" Tau and rv-31 dvd player. I also have a kenwood Kenwood SW-303 sub. My room is aprox. 11x14 feet. I`m looking for a receiver speaker package to complement what I currently have. This will be my first HT system. I was considering the Yamaha AV-R520 with Polk RT35i up front with the CS-245 center and f/x300 for the rear. Is this a good comb? Should I also consider other receivers and speakers? Thanks for your advice.
